Mickey7 is a novel based on a disposable employee on a human expedition sent to colonize the ice world Niflheim. Every time there's a mission that is too dangerous-even suicidal-the crew turns to Mickey. When a particular iteration dies, a new body is regenerated with the majority of his memories intact. Following the death of six generations, Mickey7 realizes the terms of his contract and why it was the only colonial position unfilled when he took it.
